The drama kicked off on Twitter as Jemma launched a stinging attack on Katie, accusing her of trying to “turn people against” her.

She also called Katie a “s**g” and a “c***” in a foul-mouthed tweet aimed at the TV regular, before accusing her of trying to ruin her former romance with Bear.

Now things have taken a different turn as Jemma denies sleeping with Kieran.

The reality babe made a Twitter poll asking her fans if they believed she'd had sex with him.

She told Daily Star: "The reason I did the poll was because I read an article that said Katie thinks I would sleep with her husband and she was paranoid about it.

"And I thought, I'm not going to give her what she wants, which is for me to say 'I didn't do it'.

"So I thought I'd just make a poll and see what the public thinks, make a bit of a joke about it. I took it light-heartedly."

Jemma added: "I can confirm I did not. I do not goad other people's partners like Katie. I would never do that regardless of whether I dislike someone or not. I wouldn't sleep with Katie's husband."

A source had previously said Katie was worried that Jemma had been with her husband.

An insider told Now: “Katie’s wracked her brain over whether Jemma and Kieran could have ever been in the house alone. She feels Jemma could be the type to turn Kieran’s head during the height of his [sex] addiction.

“Her worst fear would be they slept together. It would serve as another blow after working so hard to rebuilt the picture perfect image of her marriage.”
